"Data centres are the new industrial infrastructure of the digital economy." Examine how state-level incentive competition shapes India's data centre landscape, and its implications for balanced regional development.

Data centres now carry India's cloud, AI and digital public infrastructure, much as ports and power plants carried industrialisation. Installed capacity reached 1.57 GW in August 2026 and is projected to reach nearly 8 GW by 2030 [2]. States are competing to host this capacity. That competition speeds up investment, but it does not by itself spread the industry evenly across regions.

How incentive competition shapes the landscape

• Policy proliferation: 19 policies across 11 states since 2016, covering IT, ITeS, data centres and GCCs [1].
• Pillar-wise contest: S&P Global's DCPAI index compares states on electricity, land and capital, operational support and EoDB. Telangana ranks first. Gujarat offers the best power and EoDB measures for hyperscalers, and Andhra Pradesh leads on land and capital support [1].
• Regulatory innovation: Karnataka offers data centres an ESMA cushion to protect them from strikes [1].
• Layered on central support: data centres have infrastructure status (Harmonised List, 2022–23) [2], and Budget 2026–27 gave a tax holiday till 2047 for cloud services provided from Indian data centres [3].
• Still incomplete: even the top four states score only about 50/100 [1].

Implications for balanced regional development

Positive

• New entrants such as Uttar Pradesh, Odisha and Haryana now rank high, which offers a chance to spread capacity beyond the old hubs [1].
• Data centres bring related GCC and ITeS investment into the same states [1].

Negative

• Concentration persists: Mumbai–Navi Mumbai holds over 25% of live capacity and Chennai about 13% [2]. Chennai is the second-largest hub even though Tamil Nadu is not in the index's top clusters [1]. Connectivity and existing demand matter more than subsidies.
• Race to the bottom: states add power and land subsidies on top of central tax benefits. This drains the budgets of poorer states, which can least afford it.
• Resource stress: cooling needs heavy power and water, often in cities already short of water. The index has no sustainability pillar [1].

Way forward

• TRAI's two-list Data Centre Incentivisation Scheme has the Centre give baseline incentives while states set fiscal incentives within central guidelines [4]. That framework can make state subsidies conditional on renewable power and water disclosure.
• States should compete on clearance speed rather than on who gives the biggest subsidy. Smaller edge data centres can be promoted in tier-2 cities.

Competition between states has given India clear policies quickly, but on its own it rewards the hubs that already exist. Combining competitive and cooperative federalism, with incentives tied to sustainability and regional spread, can make data centres resilient infrastructure in line with SDGs 9 and 10.
